The biggest thing you need to look at is the head and Make that motor breath. with good head work a cam change ( rv or little more) intake&carb along with some kinda dual exhaust,and a small bump in the compression. It will be easy to get that into the 200-250 range. depending on the yr some of the 230s had a 140-145 hp So trying to get the 200 is with in reasonable range. With out going Ape in the cam Or compression department.
God doesn't like ugly.
